The part about less tearing out on end grain... yeah, that was my breaking point too. Finally caved and got some better steel, and suddenly my joints aren't embarrassing.
Switched to some Japanese chisels with laminated steel after struggling with cheap ones. The difference was instant, with cleaner cuts and less tearing out on the end grain. Took a week to dial in the sharpening, but now my mortise walls are dead straight. What did you upgrade to?
